I have two of the recalled adatpers -- one came with the phone, and one which I bought from the apple store on line.
The Web form takes your serial number, but will not let you specify a quantity. So it will only issue one replacement. You cannot access the web form a second time, because your serial number can be used once.
The web page suggests if you are in this situation that you contact support by phone.
Support's automated line will not direct you to an operator, but insists on helping you "troubleshoot". Once it figures out you are calling about the adatper, it tells you to go to the web page.
Can you say: "recursive"
After I screamed "Agent" enough, it finally tells you there is a 20 minute hold time.
Has anyone had success ordering a second replacement?
